Abstract (en)

[origin: EP2031800A1] Methods and systems of fault location for a communication equipment are disclosed. The method includes obtaining internal test information of each FRU (Field Replaceable Units) in a communication equipment; searching all unit circuits associated with the test information according to the test information and a dependency matrix that describes the communication equipment; further searching the test information related to the unit circuit in the unit circuits set according to the unit circuits and the dependency matrix; setting up a location sub-matrix according to the searched unit circuit set and test information set; judging and logging the unit circuit having an abnormal state in the location sub-matrix; judging the abnormal unit circuit and logging the corresponding FRU according to an FRU analysis rule. The present invention associates the test or alarm information with the unit circuits in the FRU, so as to automatically locate the real faulty FRU. Overcoming the slowness of fault location in the prior art, the present invention can automatically locate the FRU, solve the time-consuming problem in fault location and locate the faulty FRU directly.
